C. L. FRINK, OF ROCKVILLE, CONNEC'I'IGUT.l

Letters ,Patent No. 61,414,'dated January 22, 1867.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, C. L. FRINK, of Rockville, in the county of Tolland, and State of Connecticut, have invented a new and useful Improvement in Globe-Valves; and I do he'eby declare that theV following is a full, clear, and exact description thereof.

My invention consists in a peculiar disk, by which l am enabled to hold the elastic packing in globe or other valves in place. v V V And to enable others skilled in the art to make and use my invention, I will proceed to decribe its constructon and operation, reference being had to the hccom'panyin g drawings, which form a part of this specification, and to the letters of reference marked thereon.

The drawing represents a longitudinal section of the cock in Figure 1 and Figure 2 is a plan or top view' of my new disk.

Similar letters indicatelike parts.

A represents the shell of' the cock. B, the valvestem with the screw. C, the female screw or nut. I), the Valve-seat. E, the elastic packing. F is a damping-plate. G is a screwwhich enters the en'd of the stem and holds the clamping-plate. H is the disk which holds the elastic packing in place.l The disk H is attaehed to the stem B by a pin which is fast in the steni, and which works in a groove made in the hole through the collar of the disk. The stem rotates or turns freely in the disk while the disk keeps its position. It'has be'en found that in` all valves'of this description the elastic packing is liable to become displa'ced and rendered nearly useless after a certain period of time,makin it necessary to renew the packing, thereby causing expense and d elay. To overcome this diificlty, I have invented and applied the peculiar-shaped disk H, as shown in the drawing. This disk is" held in position, a's before stated, by the loose attachmcnt to the Valve-red. The under side of-the diskV is 'formed as represented in the drawing, the edes or lip of which enelose the elastie packing, and prevent its spreading or odisplacement; The (damping-plate F is forced against the packing by the screw G, and this forces the packing into the recess in the disk, as seen in the drawing, thus keeping it in 'place while it adjusts itself to the Valve-seat D; l

Having thus described my invention, what I cla'm as new, and desire to secure by Letters Paten t, isz- The attachment of the disk H to the stempB, by means of the pin which is fast in the sten, and Working in a grooye in the disk, as herein shown and described. p

The above specification of my invention signed by me this 20th day of September, 1866.
